Abstract :

Abstract[1] This study was conducted to determine the muscle chemical composition (protein, lipid, ash and moisture) of Schizothorax zarudnyi and Schizocypris altidorsalis and their changes related to sex and season during the year (autumn 2007- summer 2008) in University of Zabol. The results indicated that the chemical composition of both fish depends on season and sex. There were differences in annual changes between S. zarudnyi and S. altidorsalis, as the highest moisture content and lowest protein and lipid content was observed in autumn for S. zarudnyi, while it happened for S. altidorsalis in spring. The lipid content was more in S. zarudnyi muscle than S. altidorsalis muscle. The mean, minimum and maximum protein content of S. zarudnyi muscle were 14.47 ± 0.61, 12.77 and 16.50 percent in male and 14.18 ± 0.95, 13.22 and 15.32 percent in female, respectively. The mean, minimum and maximum protein content of S. altidorsalis muscle were 14.45 ± 0.87, 13.03 and 16.27 percent in male and 14.25 ± 1.00, 13.05 and 16.04 percent in female, respectively. The effects of sex and season on muscle moisture content in both fish were significant (P<0.05). *- Corresponding Author; E-mail: [e-mail]
